# MDB + error reading

Advantages of connecting Dr.Coffee machines via MDB with error reading:

1. **Minimal disassembly required**\
   The connection for reading errors is conveniently located on the backboard of the coffee machine, reducing the need for extensive disassembly.
2. **Simplified recipe management**\
   There's no need to perform recipe learning on the controller, streamlining the setup process.
3. **Enhanced compatibility**\
   Eliminates issues related to the controller's compatibility with specific recipes, such as those involving chocolate.
4. **MDB bill acceptor integration**\
   Provides the option to connect an MDB bill acceptor, enhancing payment flexibility.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.smvend.io/equipment-installation/coffee-machines/dr.coffee/mdb-+-error-reading.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
